Chatwoot retires Captain V1 and rebuilds its AI assistant as a structured, per-assistant behavior system.
Chatwoot is in the middle of a significant architectural transition for its AI assistant layer. The original Captain V1 (free-form instructions) is being retired in the next self-hosted release in favor of a structured model with scenarios, response guidelines, guardrails, and a testing playground. Cloud users are already on the new system. Alongside this, two substantial releases expanded Captain's control surface: per-assistant custom tools, inactivity handling, and audience/schedule targeting. WhatsApp BSUID support and improved call recording controls round out a busy month in the communications layer.
Fonoster now cleans up deleted workspaces and stops exposing stored secrets.
Fonoster ships minor versions almost daily. v0.51 to v0.53 added Anthropic, Google and Groq models, TTS voice choice and one-switch call recording. From November 10, v0.54 to v0.56 added branded emails, legal pages, webhook event lookups and API key rotation, and v0.57 returns secret values only to API keys, cancels a deleted user's plan, and ends a deleted workspace's calls and resources.

Chatwoot is shifting Captain from a chatbot add-on into a proper automation layer with auditable, testable behavior. Per-assistant tool isolation, audience segmentation, and schedule-based availability bring it closer to the model used by Intercom Fin and Zendesk AI. The V1 retirement removes a backward-compatibility constraint that was slowing this transition. The playground — which lets admins test assistant configurations before saving — removes the need to test in production, which was the practical barrier to iterating on Captain.
The next likely move is a reporting layer for Captain — tracking resolution rates, handoff rates, and scenario effectiveness per assistant. The playground's 'Run details' view (showing which scenario handled a message and which tools ran) is the building block for that kind of analytics.

After a quick run of voice-AI options, Fonoster has turned to what a hosted service needs before paying customers rely on it: legal pages, billing correctness, webhook debugging and account deletion that actually removes data. The cadence stays daily and the changes stay incremental.
More account and billing lifecycle work is likely next, since v0.57 adds a billing test case and deletion rules in the same release.
